Application February 17, 1942, Serial No. 431,285

(Cl. 1GO-242) 3 Claims.

This invention relates to a roller window screen and has for its primaryobject a screen carried by a spring roller and operatively attached between the usual form of window casing and the slidable sash thereof forthe purpose of automatically positioning the screen covering the openingof varying sizes when the window is moved to its open position in thewindow frame.

A further object of the invention is the provision of a Window screennormally mounted upon a roller whereby the screen is automaticallyextended during the window opening operation and re-rolled upon theroller out of use when the window is returned to its closed position.

A still further object of the invention is to provide an automaticallyoperated Window screen adapted for use with any width of window andbeing of simple construction and inexpensive to manufacture as well asserviceable and advantageous wherever a window screen is required, andhaving adjustments furnished to accommodate diierent lengths of windowscreen ready for use and detachably mounted upon the window frame.

With these general objects in view and those that will appear as thenature of the invention is better understood, the invention consists ofthe combination and arrangement of parts hereinafter fully described inconnection with the accompanying drawing and then pointed out in theappended claims.

In the drawing:

Figure 1 is an elevational view of a window frame having the usualsliding sash and with my automatic window screen mounted thereon, theWindow being in a partially open position;

Figure 2 is a slightly enlarged vertical sectional view taken upon line2-2 of Figure 1, and looking in the direction of the arrows;

Figure 3 is a similar enlarged sectional view taken upon line 3-3 ofFigure 1, and likewise being enlarged and with parts broken away;

Figure 4 is an enlarged sectional view taken through the lower portionof the sash in its closed position with the automatic window screenentirely rolled upon its spring roller.

Referring more in detail to the drawing, there is illustrated the usualform of rectangular window frame having opposite sides III and bottom IIwith the window sill I2 carried by and forming a part of the bottom ofthe window frame.

The window sash I3 is vertically slidable in the window frame andprovided with oppositely positioned removable retaining strips I4normally overlying the opposite edges of the sash I3 which is therebyoperatively mounted for use in the frame I0 although manually removableat will.

The gist of my invention consists of a screen I5 which may be of fabricor metal or any material desired having the necessary foraminous bodystructure and with one end of the screen I5 secured to the lower rail I5as by hold-fast devices I'I passing through a binding I8 permanentlyattached to one end of the screen I5. The opposite end of the screen I5is attached to the spring operated roller or barrel Iil whereby the coilspring 29 is mounted within said barrel I9 and automatically rewinds thewindow screen I5 during the closing of the sash opening 2U. The screenI5 may be made of impregnated weatherproofed material.

The most material feature of the invention is the manner of mounting theautomatic roller I9 to the screen I5 upon the window frame Iii and thisis accomplished by a pair of attaching brackets 2| secured to theopposite inner faces 22 of the window frame lil.

The mounting brackets 2| are adjustable in height, made possible by theattaching screws 23 passing through the brackets 2| and into the adjacent face 24 of the window frame III, as best illustrated in Figs. 2and 4 oi the drawing. The position of the attaching brackets 2| isregulated when mounting the roller screen I5 upon the window frame I5and being so arranged that the complete window screen I5 may beaccommodated wound upon the spring roller I9, as shown in Figure 4 ofthe drawing.

An idler roller 25 has end trunnions for revolubly mounting the idler 25in the brackets 2l with said idler roller 25 in parallelism with springactuated mounting roller I9.

The complete operation or' the device will be at once apparent from thisdetailed description thereof, it being understood that with the screenI5 having one end attached to the lower edge or rail of the slidablesash I3, that the opening or the sash I3 pulls upwardly on the screen I5unwinding the same Irom the spring roller i9 substantially covering theopening 2d of the window frame. Upon closing the sash I6 by lowering thesame, the spring 20 of the automatic roller I9 rewinds the screen I5upon said roller I after the manner of a window shade or other springmounted automatically operated roller.

It will be apparent that by releasing the set screws 23 for the brackets2| that the relative positions of the roller I9 and roller 25 may bemade to accommodate different forms of window screen as well as toaccurately adjust the mounting bracket 2| to accommodate the screen l5when completely rewound upon the spring roller I9 with the window sashI6 in its lowered closed position.

While the form of the invention herein described and illustrated isbelieved to be the preferable embodiment of the invention, it will beunderstood thatv minor' changes can be made in the form proportions anddetails of construction without departing in any manner from the spiritand scope of my invention.

I claim: i l

1. In a roller window screen of the character described, a mountingbracket adjustably secured to a side of a window frame adjacent thelower end thereof, a screen roller'and a guide roller for the screenjournaledI at one end insaid bracket, the adjustable mounting for saidbracket including la'screw;between the endsrthereof about which thebracket may be held to posi-- tion the axis r,of the screen roller at agreater distance from the window 'sill than the maximum radius of thescreen Wound on the screen roller.

2. In a roller window screen of the characterdescribed, a mountingbracket adjustably secured to a side of a window frame adjacent thelower end thereof, a screen roller and a guide roller for the screenjournaled at one end in said bracket, the bracket comprising a platehaving end anges for engaging the adjacent side of a window frame andprovide projection space for the journal pins of the screen and guiderollers. 3. In a roller window screen of the character described, amounting bracket adjustably Secured to a side of a window frame adjacentthe lower end thereof, a screen roller and a guide roller for the screenjournaled at one end in said bracket, the adjustable mounting for thebracket including a screw between the ends thereof aboutwhich thebracket may be pivoted to position the axis of the screen roller at agreater distance from the window sill than the maximum radius of thescreen wound on the screen roller, thebracket comprising a plate havingend anges for engaging the adjacent side of the window frame to spacethe plate from the window frame and provide projection space for thejournal pins of ythe screen and guide rollers.
